Do you want to know the difference a few dollars can make? · Do you wish you could cut your energy saving bills by 10 to 17%? · Do you wish that you had more control over where your hard earned money is being spent ?
Radiant Barrier could be the answer to
all your questions. Radiant barrier is a
reflective insulation system that offers
a permanent way to reduce energy costs.
Radiant barrier insulation systems
reflect radiant heat energy instead of
trying to absorb it. A pure aluminum
radiant barrier reflective insulation is
unaffected by humidity and will continue
to perform at a consistent level no
matter how humid it may be. A radiant
barrier insulation system is a layer of
foil facing an airspace and is installed
in the envelope of a building.
A radiant barrier reflects radiant heat energy instead of trying to absorb it. What does this mean in your home or business? During the winter, 50-75% of heat loss through the ceiling/roofing system and 65-80% of heat loss through walls is radiant. In the summer, up to 93% of heat gain is radiant. If you are depending on R-value (resistance) alone to insulate against heat gain and loss, remember that traditional forms of insulation are virtually transparent to radiant energy and are affected by changes in humidity (moisture levels). A 1-1/2% change in the moisture content of fiberglass insulation will result in a 36% decrease in performance (referenced from HVAC Manual 10.6; McGraw-Hill). A pure aluminum radiant barrier is unaffected by humidity and will continue to perform at a consistent level no matter how humid it may be. Keeps Summer Heat Out, Winter Warmth In Most people are familiar with traditional insulating materials such as fiberglass, cellulose, Styrofoam, and rock wool. These products use their ability to absorb or resist (slow down) convective and conductive heat transfer to insulate (R-value). A third, seldom discussed but dominant form of heat transfer exists: radiant heat transfer. What are the differences among the three forms of heat transfer?
